Practical guidance
When to book the clinic
Book a travel-health clinic appointment 6 to 8 weeks before departure for Thailand. Several recommended vaccines (Hepatitis A and B, Japanese Encephalitis, rabies pre-exposure) need a multi-dose schedule that does not compress; the full course can take 4 to 6 weeks. Yellow fever specifically takes 10 days to confer immunity and certificates are only valid 10 days after the shot, so this one is non-negotiable on timing.
Yellow fever specifics for Thailand
Yellow fever proof is required only if you have transited or stayed in a yellow-fever-endemic country in the 6 days before arriving in Thailand. If your itinerary is direct from a non-endemic country, no certificate needed; if you are routing via Brazil, sub-Saharan Africa, or northern South America, carry the ICVP.
What “recommended” actually means
The 4 recommended vaccines above are the CDC and WHO guidance for typical travellers to Thailand. They’re not mandatory at the border; they protect against the diseases endemic to the region. Routine immunisations (MMR, dTaP, polio, COVID-19, annual flu) should already be current regardless of destination. Hepatitis A is the single highest-value travel vaccine for most destinations, transmitted through contaminated food and water, and worth getting even if you only plan to eat in established restaurants.
Cost and where to get them
UK NHS travel clinic is free for routine vaccines, charged at cost for travel-specific ones (yellow fever, Japanese Encephalitis, rabies). US travellers should expect $100 to $300 per dose at a travel clinic; many are not covered by standard health insurance. Cheaper option in some destinations: get yellow fever locally at a government clinic on arrival ($20 to $50 in most South American and African capitals) if your itinerary allows the 10-day window before your next entry. Always ask for the official yellow ICVP booklet, not a generic clinic slip.

More on Thailand
Thailand is broadly safe for tourists but the pattern is unlike any of the other top-tier travel destinations. Violent crime is rare; what kills foreigners is motorbikes, water, drink-spiking, and a handful of well-documented scam ecosystems. The southernmost three provinces carry an active separatist insurgency and are the only do-not-travel zones in the country. This guide unpacks each, plus the lèse-majesté law, the medical-tourism infrastructure, the visa quirks for long stays, and the season-by-season weather story that shapes everything else.
